Early 2011 Macbook Pro, macOS Sierra 10.12.6. Somehow a program called Clover got installed on my machine and I think it's causing some issues. I didn't install it (according to my memory), but I want it gone as it seems to be screwing around with a few things. I use my MBP in clamshell mode, with external peripherals, and lately whenever it goes to sleep after 15mins or so, I can't wake it up and have to restart it. I became aware that Clover was on the machine after the first time this happened, as a "Clover" splash screen with boot options came up. I had no idea what it was. The other thing I've only just noticed is, when I click on "About this Mac", I get incorrect, info. It says it's a iMac (27-inch, Late 2013), which it's not. So how do I get rid of this thing and get everything back to normal?
